Taconite heavy conveyor seals

Fine-grained taconite is extremely difficult to keep out of bearing arrangements, particularly in mining or bulk port environments. Labyrinth seals are up to the task, and even more effective when used with grease, which enhances the sealing effect and is helpful in the presence of taconite.

The taconite seal design is based on a labyrinth seal with the labyrinth stages arranged axially. A special solution prevents contaminants from penetrating to the bearing when the seal is relubricated. Fits standard SNL and SAF housings. Depending on conveyor requirements, there are two different designs.

Taconite heavy-duty seal with a radial labyrinth

Angular misalignments of the shaft of up to 0,5° are possible. The permissible operating temperature range for the seal is between -40 °C and +100 °C. The axial movement of the shaft relative to the housing is limited for this type of taconite seal to +/- 1,2 mm for shaft diameters up to 100 mm and +/- 1,5 mm for larger shaft diameters.

Taconite heavy-duty seal with an axial labyrinth

The axial movement of the shaft relative to the housing is limited for this type of taconite seal to +/- 2 mm for shaft diameters from 150 mm up to 200 mm and +/- 4 mm for larger shaft diameters.
